Modern feel and our exclusive hollow core ken design. 

As you may know, balance hole makes kendamas better for lunars by reducing weight from the basecup. The problem with having the basecup hole at the surface will reduce the momentum of the ken when doing kenflips, taps and slingers, not to mention difficulty for any finger tricks.

With the hollow core design, we drilled a bigger balance hole, and covered the surface while leaving an empty space inside the ken. This gives you an all-around ken shape for all players.
